“…The suspension performance is evaluated by calculating the root mean square value (RMS) of the International Organization of Standardization (ISO) weighted vehicle body acceleration a RMS , RMS of the suspension travel S RMS and RMS of the dynamic tyre load D RMS =ẍ 1 /g [11] . The vehicle is assumed to move at the speed of 45 km/h over a medium road surface [8] (similar to E degree road surface). The parameters used in the simulation are listed in Table 1.…”

“…The switchable stiffness and damper system is a class of suspension systems, of varying complexity, which occupies the gap between passive and active suspension systems. In contrast to the full-active suspension, this system is only capable of dissipating energy and the force generation has to be modeled by a rule based strategy [7][8] .…”

“…Undoubtedly, this system does not provide the best ride comfort, handling and stability. In order to improve both ride comfort and handling, many kinds of active suspensions have been developed in the past years [3][4][5][6][7][8][9] . However, the active suspension system is found too expensive and complex in solution, and also it requires an auxiliary external power supply, so it is seldom applied except for some luxury cars and military vehicles.…”

A twin-accumulator hydro-pneumatic suspension has been developed based on the off-road vehicle in order to meet the requirements of ride comfort. The working principle and elements construct of the developed suspension are studied. And then, a mathematical model of the developed suspension is built. The influence of twin-accumulator hydro-pneumatic suspension parameters on the vehicle body vertical acceleration, suspension travel and dynamic tyre load is studied by simulation based on a quarter off-road vehicle model. The ride comfort of the vehicle with the developed suspension is studied by a theoretical evaluation; also the ride comfort of the vehicle with twin-accumulator hydro-pneumatic suspension is compared with the one with single accumulator hydropneumatic suspension in both time domain and frequency domain. The result shows that the twin-accumulator hydro-pneumatic suspension system gives worthwhile improvements in ride comfort compared with the single accumulator hydro-pneumatic suspension, and it is more suitable for off-road vehicle.
